if you subscribe to his newsletter, you will read almost verbatim "this is a one man operation and I'm doing the best I can. Sorry for the delay."

It seems to me, that for a very small operation, giving everyone the option to subscribe to a newsletter is much more efficient than answering hundreds of individual e-mails asking why they don't have the materials they ordered in their mailbox. I just got a new newsletter a couple hours ago in fact. Says he is currently about 5 days backlogged on orders right now.
